CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a Divisional application of U.S. application Ser. No. 14/246,221 filed Apr. 7, 2014, which claims the benefit of U.S. Provisional Application Ser. No. 61/809,500, filed on Apr. 8, 2013, all of which are herein incorporated by reference in their entireties.

FIELD OF THE INVENTION

The present invention relates to food processors and, more particularly, to a food processor having an external slicing disc adjustment mechanism.

BACKGROUND OF THE INVENTION

Food processing devices providing a number of different types of food preparations, such as mixing, grinding, chopping, slicing, grating, shredding, or other processing operations, are well known. Existing food processing devices typically include a base housing an electric motor, a drive shaft driven by the motor, a bowl receivable on the base and a lid or cover having a feed tube releasably mounted to the bowl. A rotatably driven blade is mounted to the drive shaft to process one or more food items inside the bowl.

While existing food processing devices are generally suitable for what is regarded as ordinary performance, there is room for improvement in terms of ease of use and expanded functionality. In particular, a limitation of existing food processing devices is that when utilized with a slicing disc, they must be turned off and the blade assembly removed in order for a user to manually adjust the slicing thickness on the blade.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a food processor having a mechanism for adjusting the slicking thickness of a slicing disc.

It is another object of the present invention to provide a food processor having a mechanism for externally adjusting the slicing thickness of a slicing disc.

These and other objects are achieved by the present invention.

According to an embodiment of the present invention, a food processor having an external slicing disc adjustment mechanism is provided. The food processor includes a work bowl and a lid configured to be selectively removable therefrom. The food processor further includes a slicing disc having a disc body and a slicing blade internal to the work bowl, and a mechanism for adjusting a spacing between the disc body and slicing blade. The mechanism includes a rotatable lever accessible form outside the work bowl.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, a food processor 10 according to the present invention is shown. The food processor 10 includes a base 12, a work bowl or receptacle 14 received on the base 12, and a lid 16 configured to be selectively removable from the work bowl 14. Base 12 includes a motor or other rotary drive mechanism (not shown) connected to a rotatable output shaft 18 for rotatably driving a blade interior to the work bowl 14 and may include controls (not shown) for varying settings of the motor.

As further shown therein, work bowl 14 is generally cylindrical or frusto-conical in shape and has a handle 20 and a pour spout (not shown). The lid 16 defines a substantially circular body sized and is dimensioned to cover work bowl 14. The lid 16 also includes a feed tube opening (not shown). The feed tube opening may be generally oval in shape, although other shapes and dimensions are envisioned without departing from the broader aspects of the present invention.

As best shown in FIG. 1, the lid 16 may also include a feed tube 22 defining a substantially annular body having a substantially oval cross-section extending upwards from the lid 16 and in communication with the feed tube opening. As is well known in the art, the feed tube 22 provides a chute through which a user may load food items to be processed into the work bowl 14.

Turning now to FIG. 2, an enlarged view of the lid 16 of the food processor 10 is shown. As shown therein, the lid 16 includes a mechanism for adjusting slice thickness when the food processor 10 is utilized with a slicing blade 24. In particular, the slice thickness adjustment mechanism includes a lever 26 that is accessible from the top of the lid 16. The lever 26 extends through the center of the lid 16 and is rotatable between a variety of positions, marked 1-8 in FIG. 2, which correspond to various slice thicknesses.

With reference to FIG. 3, the lever 26 is coupled to a rotatable adjustment mechanism 28 which is, in turn, attached to the slicing disc 24. In the preferred embodiment, the adjustment mechanism 28 takes the form of a linear screw drive. The rotatable adjustment mechanism 28 is driven by the lever 26 to raise or lower the disc body 30 of the slicing disc 24 relative to the blade 32 of the slicing disc 24 to adjust the spacing therebetween. Alternatively, the adjustment mechanism 28 may be driven by the lever 26 to raise or lower the blade 32 relative to the disc body 30 to adjust the spacing therebetween.

Turning now to FIGS. 4 and 5, adjustment of slice thickness is illustrated. As shown therein, rotating the lever 26 actuates mechanism 28, thereby enabling a user to control the gap between the slicing disc body 30 and the slicing blade 32 to adjust the thickness of slices. As will be readily appreciated, slice thickness can therefore be adjusted from outside the bowl 14, while the lid 16 is closed.

Although this invention has been shown and described with respect to the detailed embodiments thereof, it will be understood by those of skill in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed in the above detailed description, but that the invention will include all embodiments falling within the scope of this disclosure.
